22_39b/2010Structural Color: Encoding Localized Strain History Through Wrinkle Based Structural Colors (Adv. Mater. 39/2010)

Spatially localized surface wrinkles are created on a metallic film supported on a shape-memory polymer substrate. The wrinkle wavelength approaches that of visible light, resulting in diffraction colors. The spatial and geometric distribution of the wrinkles can be controlled in an arbitrary fashion, allowing the capture of a three dimensional image on a macroscopically flat surface, as reported on p. 4390 by Tao Xie and co-workers.
